Hi Luke and welcome to Coffeeforums.
Do you normally sell out of your day old bakery items before they become two day old?
Check with local soup kitchens, livestock farmers, charities, etc. They'll pick up thetwo day old stuff.
Best thing to do is to probably get a tighter grip on what you're able to sell each day, cut back on that a little and just let it run out by the end of the day. Otherwise, you're giving your customers an incentive to come back tomorrow and get their stuff half price.
Third option, dump the muffins & donuts and go with some durable & shelf stable Italian biscotti. I hear they serve quite well with coffee.

Good luck with it and again, welcome to the forum.
